314mm utoz j z l vmw d (Rio-Luci to the eat that the. shank is formed gradually into the eides of the shzml: nee-I- the fiat portion 2 and 8. This construction not only enables the shank to be readily 1 serted between the innol sele and outer sole of a boot 01' shoe, but it also 'pleeee the greater de th of the flange where the maratmmte behcing stresses occur. It will else be observed that the Width of the shank mall increases toward the opposite ends theieof, being the least Where the flanges have the greatest depth.

A strip 6 of some'suiteble n'mtez'iel eileli leetllei, leather board, metal or wood located between the .reinforeieg 2" and 2 and corresponds in shape to that of the body of the shank; It will also be observed that the filling strip gradually ereesee in tl'zickness'towerd the opposite ends thereof, and has its mexin'u'nn thickness at the-poiot where the flanges 2 have a. .m' i imore depth. Ci-Wing to this construction. the filling strip 6 exeetly fills the space between the fienges 2 and euterfeee thereof lies flush with the edges of the flanges.

The filling strip 6 fills the shank l and eonsequently firmly holds the some in position. The filling strip 6 may be made from Wood or other stiff materiel thet will asset the shank 1 in. SUPPOIlJlIL the mob of the feet and in holding the sine rigidly in emu-set poeitio'n.

In applying the shank to a shoe, ti: Sam is interposed between the outer sole 7-9.2. inner sole 8, end is held. seeuyely in pos tion by means of? fastening memberseueh as rivete 9 passing through the three before mentionecl memoers. I One of the rivets E is tiesigned. to go through the three substances under the heel. This is provided so that the shoe would be stifi'ened for effectually ventirm any undue lateral twisting. (l-wiiig 017' e oompei'etively soft 0 1' untempered metal, the same. can be drilled to form the rivet ings ei'te'i being laced in position bet een the inner sole an outer sole, thereby obviet ing the greet ditiieuity which would 0 Wise be caused in bringing the openim, the verioue members into iegisti l elienk is formed of untemyerecl. or t. tivel r soft metal, and by reason of e may conform to the'ourvetureel t This advantage is not obtainable -m-- pered shank as the spring of the some wil not permit the conformation to the object-to which the same is secured. f

Where the shank islermed of tempered metal} as is commonly the ease, the said metal must be punched before being temperecl, and owing to the difficulty of causing the openings to register with each other, it hes becorlie customary to rivet the shank to the outer sole only.
